Average Bench 62.1%

We really like this drive, it's one of our favourites. The JetFlash 780 has superb benchmark scores, at 170 MB/s this drive has the highest sequential read score we have ever seen on a consumer grade flash drive. Very interestingly the performance profile on our test unit exceeded even the manufacturers claimed speeds by over 30MB/s! The 4K write speed is less impressive, but passable at 0.3 MB/s. With reasonably solid all round performance and a reasonable price point of £23 this drive represents outstanding value for money. [Jun '12 USBFlashPro]

The benchmark scores for the SanDisk Extreme were stunning. Until now every flash drive we have tested has shown a serious weakness in the area of 4K random writes. The SanDisk Extreme achieved a 4K random write speed of 2.1 MB/s which was over three times faster than the best of the rest, unfortunately we were unable to get consistent measurements but 2.1 MB/s was towards at the lower end of the range (10.8 MB/s - 1.71 MB/s) we observed. We suspect the inconsistency relates to the way the controller batches page cleanup. The other benchmark observations were all consistent and to date this drive has the highest sequential read we have seen on a 16GB flash drive. The SanDisk Extreme has not been released in the UK. Our test unit had to be shipped from Hong Kong where we were able to purchase it at at an extremely reasonable price. We will update the price if/when the drive becomes officially available in the UK ... [Jul '12 USBFlashPro]

ALL FAQs »

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
